the patio/fire escape stairs to the second floor (and the escape ladder to the ground floor), and

the roof hatch.

Once on the third floor, there are two other doors:

The south door from the third floor elevator landing, and

the east gate from the third floor elevator landing.

There are also a basement and a roof which are off-limits.

Front Gate

Connects To: Outside, Front Door.

The front gate is an iron gate with an electronic latch driven by the intercom pad next to the north stairwell door. This door uses a Spark brand lock. The lock uses a Schlage-style ward with pins 73655 (tip to shoulder.) We share this lock with our neighbors on the 2nd floor and the landlord.

Front Door

Connects To: Front Gate, North Stairwell Door, Elevator.

The front door is a pair of glass doors, each with a lock near the floor to drive a pin into the ground. Both cylinders use Schlage-style wards with pins 42466 (approx.)

North Stairwell Door

Connects To: Front Door, Elevator, Noisebridge.

This door uses generic Schlage compatible wards and uses the standard Noisebridge version A key.

Elevator

The elevator takes about 33 seconds to go between the first and third floors, while walking at a normal pace up the stairs takes about 20 seconds. Thus, the stairs may be used more often than the elevator for members without bicycles.

Patio

Connects To: Second Floor Landing, Roof.

There's a sliding glass door which leads to a scary metal fire escape outside. The fire escape has stairs that go to another sliding glass door on the second floor which you aren't going to use. There is also an escape ladder on that same second floor landing which you are going to use if the building is on fire.

South Stairwell Door

Connects To: Noisebridge, Outside.

This goes down two floors and dumps you in a little area that seems to have been commandeered by some rats and flies. There is also fruit. In theory you can get out of the building through here, but you're probably not going to be happy about it. Make sure you don't end up stepping on any of the mouse traps.

Northeast Stairwell Door

Connects To: Noisebridge, ???

I think this dumps you onto the second floor but the door is locked from the other side. You probably don't want to screw with this door.

Roof

Connects To: Roof Hatch, Patio.

You see a roof. There are skylights here. You feel cold. Exits are: west.

South Elevator Landing Door

Connects To: Elevator, Noisebridge.

Locked with a Schlage BE365. Use your regular 83c key to turn the tumbler 90 degrees, then push it in to engage the thumbturn with the locking mechanism. The door is currently a little out of alignment so you might have to tug upwards on the doorknob to get the bolt to engage.

East Elevator Landing Gate

Connects To: Elevator, Noisebridge.

Another ghetto installation job using one of the Spark Schlage knockoffs. Use your 83c key. Movement towards the elevator doesn't require a key.
